Bershire Grey Exercise

Prerequisites Installs on local desktop:

1. Installed Chocolatey package manager for Windows: https://chocolatey.org/install
2. Installed k3d using Choco
3. Installed Docker Desktop Hint: This may be required as virtual is required for docker engine to work PS C:\WINDOWS\system32> bcdedit /set hypervisorlaunchtype auto The operation completed successfully.

PS C:\Users\adeba> wsl -l -v NAME STATE VERSION

• Ubuntu-22.04 Running 2 docker-desktop Running 2 docker-desktop-data Running 2 PS C:\Users\adeba> Note Docker Engine won't stay up until docker-desktop and docker-desktop-data need to be RUNNING - spent time troubleshooting Engine NOT coming

Installation and Setup:

1. Create Dockerfile and copy html (pre-created) to the same folder

2. Builder file and test docker build -t bayo-nginx:v1 .

3. Create private registry k3d registry create test-app-registry --port 5050

4. Create registries.yaml (file in folder)

mirrors: "localhost:5050": endpoint: - http://k3d-test-app-registry:5050

5. Create new cluster with registy:

k3d cluster create seyicluster -p "9900:80@loadbalancer" --registry-use k3d-test-app-registry:5050 --registry-config registries.yaml

k3d node edit k3d-seyicluster-serverlb --port-add 80:80

Hint: Ran docker ps to see all port mappings with the load balancer

6. Tag and push the image to the local registry created

docker tag bayo-nginx:v1 localhost:5050/bayo-nginx:v1 docker push localhost:5050/bayo-nginx:v1

7. Create a new deployment and service using node port:

kubectl create ns bayodev

kubectl create deployment bayo-web-server-deployment --image=k3d-test-app-registry:5050/bayo-nginx:v1 -n bayodev

kubectl create service nodeport bayo-web-server-svc --tcp=80:80 -n bayodev

Note: Converted everything to attached .yaml files

Hint: To switch bayodev namespace as context: "kubectl config set-context --current --namespace=bayodev"

8. Create Ingress resource for service:

cat bayo-web-server-ingress.yaml apiVersion: networking.k8s.io/v1 kind: Ingress metadata: name: bayo-web-server-ingress namespace: bayodev spec: rules:

• host: localhost http: paths:
  • backend: service: name: bayo-web-server-svc port: number: 80 path: / pathType: Prefix

kubectl apply -f bayo-web-server-ingress.yaml
